Abstract: The device has a cartridge defined by a central body, and by a first and second cover body closing the axial ends of the central body; a first fitting formed in the first cover body to permit liquid flow into the cartridge; a chamber defined between a plate installed at a first axial end of the central body, and the inner wall of the first cover body; a tube bundle defined by capillary fibres having first axial ends fitted to the plate and communicating hydraulically with the chamber, and occluded second axial ends located at the second cover body; a membrane housing the tube bundle; and a second fitting formed in the central body to permit outflow of the liquid which has undergone a first filtration through the thickness of the capillary fibres, and a second filtration through the membrane.

Abstract: A device for concentrating solute-containing solutions, e.g. macromolecular sample solutions, by filtration through a semipermeable membrane, which device enables the user to obtain various different retentate concentrations by placing the device in different positions before use.

Abstract: Disclosed is a gravity flow fluid balancing system that includes an infusion line to transport an infusate from an infusate supply to a patient's body and an ultrafiltrate line for transporting ultrafiltrate from the body to an ultrafiltrate reservoir. The infusate and ultrafiltrate reservoirs are each connected to a load cell. The load cells are, in turn, connected to a control unit which compares the readings received from the load cells. A clamp, which is controlled by the control unit, controls the flow out of the infusate reservoir into the patient's body. Control of the clamp and fluid flow through the system can be regulated on a weight change basis (infusate - ultrafiltrate) or on an infusion basis.

Abstract: Disclosed herein is a hemodiafiltration cartridge and apparatus and methods utilizing said cartridge. Said cartridge comprises: a dialysate inlet; a dialysate outlet; a blood inlet; a blood outlet; a first semipermeable membrane means for sterilizing and depyrogenating dialysate prior to its contact with blood; and a second semipermeable membrane means for the removal of wastes from blood.

Abstract: The invention concerns a haemodialyzer of the type comprising a semipermeable flattened tubular membrane wound in spiral configuration from one end with an interposed insert around a mandrel member, means for connecting the interior of said membrane at its ends to conduits for the admission and discharge of blood, the assembly being housed in a casing in which said mandrel member comprises at least two similar elongated elements which are connected together.
